METALLIC RAILWAY-TIE.

SPECIFICATION forming part of Letters Patent No. r759,669, dated May 10,1904.

Application filed February 16,1904. Serial No. 193,323. (No model.)

To all whom t may concern.-

Be it known that we, SAMUEL H. OAUFMAN and JOI-1N BALDT, citizens oftheUnited States, residing at Chester,` Delaware county, State ofPennsylvania, have invented a new and useful Improvement in MetallicRailway-Ties, of which the following is a specification.

Our invention relates to metallic railwayties. It provides a tie with awater-shedding surface, with a rib the depth of which is decreased atits middle point to provide a certain resilience to the tie, with a boxor recess to hold a rail-seat of sound-deadening or electrically-insulating material, with proper strengthening means beneath said box,witha novel form of clip for the [langes adapted to rail-llangcs ofdifferent widths, with a novel engagement between the tie and the clip,and

y with novel means for securing such clip in position.

,lt further consists of novel features of construction, all as will behereinafter fully set forth.

Figure 1 represents in plan view a portion of ametallic railway-tieembodying our invention. Fig. 2 is a vertical section through the line.fc m, Fig. 1. AFig. 3 is a similar vertical section showing amodilication. Fig. 11 is an end view of the form of the device shown inFig. 1. Fig. 5 is a transverse section through the line .1/ y, Fig. 2,with all the detachable parts removed. Fig. 6, on a reduced scale,represents the entire device.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, 1 designates the top plate of a metallicrailway-tie, which may well be of cast-steel or similar material. Asshown, its faces 2 and 3 are slightly inclined, and an end portion l hasa similar incline, so that the tie will shed water in all directions.Running longitudinally of the plate is a llange 5, the portion (i ofwhich is reduced in depth from the bearing-points toward the center, asclearly shown in Fig. 6 of the drawings. At a distance apartcorresponding to the gage of the railway are recesses or boxes 7, openat their upper sides and provided with horizontal flanges 8. Beneath theboxes 7 are transverse ribs 9. Projectingfrom each side of the boxes 7are recesses 10, having an undercut portionV 11, as clearly shown inFigs. 2, 3, and 5 of the drawings. The boxes 7 are adapted to holdblocks 12, which may be ofwood, Vulcanized liber, or othersound-deadening or in sulating material. As shown, these projectslightly above the flanges 8 and form a base on which is laid the flange13 of the rail 14, the width of the block being substantially that oftheflange. Adjacent each recess 1() on the upper side of the flange 8 isformed a plurality of transverse grooves 15, at the ends of which arepreferably provided longitudinally disposed lugs 16. The clip 17, havinga tongue 18 adapted to engage over the railllange 13, is provided at itslower side with corresponding eorrugations 19. rlhe clip 17 islongitudinally slotted at 2O to pass a bolt 21, lthe head 22 of whichengages in the undercut portion 11 of the recess 10 inthe tie 1. A nut23, engaging with the bolt 2l, serves to hold the clip 17 in position.It will be seen that the head 22 of the bolt extends forwardly andlaterally and that its rear sid c is rounded to permit it to enter therecess 10 after the blocl 12 has been placed in position. y

The operation is as follows: The tie 1 having been properly laid andleveled, the blocks 12 are placed in the recesses 7 and the rail 111laid. The bolt 21 is then passed down through the recess 1() and itshead 22 engaged against the upper side of the undercut portion 11. Theclip 17 is then put in place, with the tongue 18 engaging' with theflange of the rail, and forced inward toward the rail as far as possibleand the nut 23 iirmly secured on the bolt 21 in any desired manner. Itwill be seen that the corrugations 19 of the clip 17 engage with thecorrugations 15 of the llange 8 of the tie, so that the clip may bemoved longitudinally of the tie to provide for a difference in the widthof the rail-tracks or curves. It will also be seen that the clip 17 isl'rmly engaged between the longitudinal lugs 16 on the flange 8, so thatany movement of the clip laterally of the tie is absolutely prevented.

1n Fig. 3 of the drawings l have shown a slightly modilied form ofconstruction :in which the contacting surfaces of the flange 8 TOOy andthe clip 17 are smooth, the upper surface of the clip being corrugatedto engage with a similarly-corrugated washer 24C, interposed between theclip and the nut 23. It will be seen that, as before, provision is madefor movement of the clip longitudinally of the tie and for preventingaccidental displacement.

Itis evident that the block 12 may be used not merely as a preventive ofexcessive vibration and consequent noise, but also to insulate the railelectrically. In this case it will of course be necessary to provideinsulation either between the iiange 13 of the rail and the clip orbetween the clip and the tie. As these methods are well known and formno part of our invention, we have not deemed it necessary to illustratethem.

B y cutting away the central portion of the iange 5, as shown in Fig. 6of the drawings, the resiliency of the tie is very much increasedwithout lessening its strength.

It is evident that various changes lmay be made by those skilled in theart which may come within the scope of our invention, and we do not,therefore, desire to be limited in every instance to the exactconstruction herein shown and described.

Having thus described our invention, what we claim as new, and desire tosecure byLetters Patent, is-

1. A metallic railway-tie comprising a top plate and suitable sti'eningmeans, said top jacent said block, in combination with means forsecuring the rail to the tie.

4C. A metallic railway-tie comprising a plate, longitudinally-disposedlugs on said plate and transverse corrugations intermediate said lugs,in combination with a rail-clip adapted to seat between said lugs andhaving on its lower face transverse corrugations adapted to engage withthe corrugations on said plate and a bolt for securing such clip to saidplate.

5. A metallic railway-tie comprising a plate, longitudinally-disposedlugs onv said plate and transverse corrugations intermediate said lugs,in combination with a rail-clip adapted to seat between said lugs andhaving on its lower face transverse corrugations adapted to engage withthe corrugations on said plate, said clip having an elongated'bolt-receiving aperture therethrough.

6. A metallic railway-tie comprising a plate provided with a recessadapted to retain an insulating-block and an undercut bolt-receivingrecess communicating with said iirstnamed recess.

7. A metallic railway-tie comprising a plate having a plurality oftransverse corrugations and longitudinally-disposed ribs at each end ofsaid corrugations and an aperture adjacent said corrugations forreceiving a clip-engaging bolt.

8. A metallic railway-tie comprising a plate provided with a recessadapted to retain an insulated block and an undercut bolt-receivingrecess extending laterally Jfrom said firstnamed recess in combinationwith a bolt, the body of which is adapted to pass into said recess andwhich has a head laterally and for-- wardly extended from said body.
